Its niche is Intel Mac dual-boot maintenance, where legacy BIOS-style operating systems expected an MBR view of a disk that was really partitioned with GPT. ### Project history rEFIt began as an EFI boot menu and maintenance toolkit for Intel Macs. Its version history records a first public release on 2006-03-02 and says version 0.7, released on 2006-05-14, added a tool to synchronize GPT and MBR partition tables. The rEFIt project later stopped active maintenance and pointed users toward rEFInd, a fork. gptsync remains packaged separately in Homebrew as a small system utility extracted from that older rEFIt codebase. ### Adoption history gptsync mattered most during the Intel Mac and Boot Camp era, when hybrid GPT/MBR layouts were a practical compatibility layer for booting Windows or other legacy systems. The tool's adoption is therefore narrow but historically useful: it appears in package managers because disk-repair and dual-boot workflows sometimes need the utility without installing the full rEFIt boot menu. ### How it is used The utility reads a device's GPT partition table and synchronizes the legacy MBR view. It is a low-level disk tool, so usage belongs in recovery, bootloader, or dual-boot maintenance contexts rather than routine application workflows. ### Why package nerds care gptsync is a classic small extracted utility: package managers keep it around because it solves a specific historical systems problem and has almost no substitute inside general application stacks. ### Timeline - 2006-03-02: rEFIt 0.1 first public release. - 2006-05-14: rEFIt 0.7 adds the GPT/MBR synchronization tool. - 2007-03-25: rEFIt 0.9 improves gptsync filesystem and partition handling. - 2010-03-07: rEFIt 0.14 adds support for additional partition types in gptsync. - 2013-03-29: rEFIt site states the project is no longer actively maintained and points users to rEFInd. ### Related projects - rEFIt is the parent EFI boot menu and maintenance toolkit. - rEFInd is the successor fork named by the rEFIt project page. - GPT fdisk solves adjacent GPT and hybrid-MBR maintenance problems, but it is a separate project. ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** gptsync - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [gptfdisk](https://www.automicvault.com/pkg/brew/gptfdisk/) - Shares av.db curated category or tags: cli, gpt, mbr, partitioning, storage. - [chkbit](https://www.automicvault.com/pkg/brew/chkbit/) - Shares av.db curated category or tags: cli, storage, system. - [device-mapper](https://www.automicvault.com/pkg/brew/device-mapper/) - Shares av.db curated category or tags: cli, storage, system. - [di](https://www.automicvault.com/pkg/brew/di/) - Shares av.db curated category or tags: cli, storage, system. - [disktype](https://www.automicvault.com/pkg/brew/disktype/) - Shares av.db curated category or tags: cli, storage, system. - [dua-cli](https://www.automicvault.com/pkg/brew/dua-cli/) - Shares av.db curated category or tags: cli, storage, system. - [duc](https://www.automicvault.com/pkg/brew/duc/) - Shares av.db curated category or tags: cli, storage, system. - [f3](https://www.automicvault.com/pkg/brew/f3/) - Shares av.db curated category or tags: cli, storage, system. ## Combined YAML source View the package source record on GitHub.
